DECK-EASE SUPPO'RT.

To all whom it may concern Be it known that I, THOMAS A; Laser, a citizen of the United States, and resident'o-f Chicago, county of Cook, and State of lilinois, have invented certain new and useful Improvements in Deck-Sash Eiupports, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to deck sash sup ports of the ratchet sector type. Its object is to provide means for pivoting the sash such that it may be readily removed, and at the same time to design such means as to firmly hold the sash against lateral move ment when in place in the window frame. A further object is to provide a novel form of ratchet sector which will aid in securing the sash against lateral movemenhend to provide means for raising and securing the pawl or plunger out of engagement with the ratchet sector when it is desired to remove the sash from the window frame.

In the accompanying drawings:

sash provided with the improved supports and secured in place in a window frame:

Fig. 2 is a side view of that portion of the supporting mechanism which is'secured to the window frame, a part thereof being shown in section;

Fig. 3 is a side view of the complete ratchet mechanism;

Fig. & is a side view of the support shown in side view in Fig. 2, portions being shown in section;

Fig. 5 is a front view of the ratchet sector; and

Fig. 6 is a side view of the ratchet sector.

As shown in Fig. 1, deck sash 10, of usual construction, such as is employed, for example, for ventilating purposes in railway cars or the like, is journaled in the window frame 11, and is normally held in desired angular position relative thereto by means of a pair of spring-pressedplungers 12, 12, projecting downwardly from housings 13, 13, the base plates of which are secured at opposite ends of the window frame 11.

The plungers frictionally engage the rounded ratchet teeth 14 of the ratchet sectors 15, 15, secured at opposite ends of the sash 10, as by means of screws 16 passing through the base plates 17, 17, of thesectors,

the base plates being preferably cast intogral with the ratchet sectors. While two sectors are here shown and described, it is evident that one might be dispensed and a journal of some other type substituted,

the single ratchet serving to hold the deck sash in its adjusted position.

Referring more particularly toFigs. 2 to 6, each ratchet sector 15 is provided with a flange 18 on its outer periphery adjacent the window frame 11. This flange prevents the plunger 12 from slipping out of engaging position with the ratchet teeth due to anv looseness in the mounting of the sash. 18

having flanged sector on. each side of the sash and the plungers 12 bearing on the inner faces of the flanges 18, the sash is positively locked against lateral movement within the window frame.

As a further means of eliminating lateral play of the sash, the trunnions 19, 19, of the sectors 15, 15, are'provided with enlarged heads 20, 20, the trunnions being T-shaped in section.

The base plate of each housing 13 extends downwardly therefrom and its lower portion is cut away, as at 21, to form a hook. That portion of each hook which is adjacent the window frame is grooved, as at .13, to ac commodate the T-shaped head of the corresponding trunnion. It will thus be seen that the trunnions of the deck sash may be readily fittedin the hooks and the sash thus rigidly held against lateral displacement by means of the closely fitting trunnion heads 20, 20, which are firmly held in the grooves 23 The housing 13, as shown in Fig. 2, is provided with aligned apertures 24, 25, through which the extremities of the bolt or plunger 12 project. At its forward end the plunger is provided with a bearing collar 26, for one end of a. coiled helical spring the other end of which bears against the top wall of the housing 13. The spring thus forcibly holds the bolt in engagement with the ratchet sector.

To facilitate the removal of the sash from the casing there is provided a shaft 29, journaled in the lower ends of the side walls of the casing 13 and offset intermediate of its ends to form a crank 30 for engagement with the collar 26. A crank arm 28 on the shaft 30 serves as means for turning the shaft to lift the plunger out of engagement with the sector 14:. When the handle 28 is jacent the frame to accommodate said enin vertical position, as shown in Fig. 8, the larged head, a housing secured to the wincrank 80 lies flat beneath the collar. When, dow frame above said ratchet sector when however, the handle is swung downwardly the deck sash is in place, a bolt carried in 4.5 the collar is lifted and the plunger raised said housing and its forward end normally from the ratchet sector, thus permitting the projecting downwardly therefrom for ensash to be removed, its trunnions eing gaging the ratchet sector, and a flange on readily lifted from the hook the periphery of said sector between the I claim as my invention downwardly projecting bolt and the winm 1.
